VALVE.

Application mega August 31, 1925. 'serial No. 531,560.

The present invention relates'to improvev ments in valves andmoreparticularly refers to av wall installation for use 1n connection ofvacuum cleaning f systems.

An object of thesinvention is to providea wall socket structure inconnection with ak source of vacuum for the attachment of a hoseconnection 1n much the samefaslnon as electric light sockets are nowprovided as wall fixtures.

Another object of the invention is topro-V vide an improved constructioninwhi'ch the socket is adapted for adjustment to accommodating walls ofvaryingthickness.

A further object of the invention is to provide an improved wall socketand com-k binedvalve structure, whereby the valve will be obscured inthe wall, buty will be renderedlA readily operable by the connectionfrom the exterior of the wall, and whereby the operator may govern theamount of air passing through the valve to the hose connection.V

AIt is a still further object of the invention to so construct andarrange the parts that the attachment may be made tothe wall socketwithout entailing any leakage of air.

Other objectsrare -to provide anineXpensive land simply constructed wallplug and valve installation with few and simple parts that may bemounted as a unit.

With the foregoing and other objects in view, the invention will be morefully described hereinafter, and will be more particularly pointedv outyinthe claims 'appended' hereto. 1

sideview of the adjustingv to receive the threaded: bolts 15, which ex.-tend through the flush plate. The sleeves. are-held together and thevalve coupled to a flush plate in this manner. Such connection permitsof adjustment for walls of varying thickness.

This valve casing 17 forms an extension ofthe pipe 19', which has theelbowV and the upwardly extendingA forward portion. providing the port.18 normally closed by the cylindrical valve body 24 adapted-f toreciprocate horizontally. The pipe 19 connectsl with a pipe line 20 incommunication with a source of" vacuum or suction. This source isgenerally located in the basement:` of the building. The pipe 19 may beprovided with the'lugs 35 to seat upon a support and Perforated threadedlugs 16 extend outwardly from the sleeve 14 to receive the screws'34 forholding the in- Y' stallation on such support.y The upper end voftheelbow above the' valve-body 24y is pro- V 1 vided withaspace 37 toreceivethe packingl 38, the packing being-'introduced' through theopening 39 at the top. Oilv may' also be introducedithrough this openingto-saturate the packingl and to lubricate the -valve body 24. Theforward edge'26rof thevvalvebodyv is'incl'ined anda pilot tip- 36 isformed on the upper outer inclined end for vthe prur-y pose of engagingthegactuating" barrel 49 as hereinafter explained. 'This'pi'lot and theinclined rend ofv the-valve body provide anextensive bearing surfaceandi prevent the valve from dropping down into the port .18.

The rear end of the valve body 24 is pro-l vided ,with' the enlargedflanged 25 toV take against the shoulder 26forn1ed'on the pipe 19,whereby to prevent the further movement of the valve toward theY wall.

The valve body carriesa hollow or squarestem 23 fitted in acorrespondingly shaped bearing- 21.v This bearing is alXedas-by thescrews 22 to the upper side of the pipe 19. A coil spring 27 Within thehollow stem urges the valve-to the closed position, shown in Figure 1.The tension of the spring may be adjusted by the screw rod 29, whichprojects through a rear Wall 32 of the housing 31, which is aliixed toappro-Y against'the adjacent end o the spring 2T.l

This Washer or head also has threaded engagement with the shaft and maybe independently adjusted there alonf to further vary the tension ofthe' spring. The tension of the spring is roughly regulated by theadjustment of Vthe Washer 30 and a nicer adjustment is secured bytherotation of the rod 29. j.

The opening in the flush plate 12 and the sleeve/,13 Vare `adapted toremovably receive the attaching or aliixed barrel 42 and to hold thebarrel in place, a pin 43 is made thereon and arranged to enter anopening 45 in the flush plate adjoining the central opening. The opening45 connects at its inner edge With a circumferential opening 44. The pin43 is inserted through the opening 45 until it reaches the opening 44and it is then turned (compare Figures l and 7). Ihe arrangement ismuchlike a bayonet joint. v

The` barrel 42 is provided with the slot 46 opening through its innerend and connecting With an inclined portion having a series of teeth 47to engage with a pin 48 projecting radiallyfrom an inner valve actuatingcylinder 49. This last mentioned cylinder 49 is fitted rotatably Withinthe atliXed cylinder 42 andthe inner end ofthe cylinder 49v is adaptedto lie adjacent and to strike the pilot 36 of the valve. f

The outer end of the affixed cylinder 42 receives the hose 40 heldthereon vby the hose clamp-4l. To the hose is connected any sort kofreceivin'g implement or nozzle to be moved over the carpet, fabric orother material to becleaned. v

The adjusting apparatus is housed by the casing 31 having the side Walls31 extend.- ing down to the upperv end of the pipev 19. The cover isopen at the` bottom and Aat one end to accommodate vthe pipe 19 and itselbow. K Y

In the use of the device the Wall and the flush plate present theappearance indicated in lf-"igure'lv and the valve 2,4 Within is closed,so that there is no communication of the room atmosphere with thesuctionapparatus. The hose'connection Vmay bekept in the closet lor other place`and produced when large amount of suction through the hose.

40 is not desirable as it will usually such the 'nap ofi" the cloth andWear it out more rapidly. For soft material, clothes etc., the

operator advances the arm 48 toward the Wall fora slight distance onlyand engages the arm with say the tooth 47. A` slight port areawvill beexposedand there 'will be a comjmratively small inrush oi air throughthe pick-up tool at the end of the hose 40. However, for cleaningcarpets and the like, Where heavy dust or mud is encountered the valveport 18 maybe-'fully opened by advancing the arm to the notch 47. J

In lligure 10 is shown a modiiication of the hose connection providedwith a locking pin 43 adapted to it in the slot 45 of the flush plate.The hose 40, 'and the clamp 41* are similar to parts already described.The barrel 60 in this ease is directly coupled to the hose and lits inthe valve casin'gil and against the valve. The shim ring 61 may be usedasa filler so that the connection will snugly lit the diameter of thesleeve 13. In the use of this connectionfno adjustment of the amount ofair entering the valve is possible, .other than to open the valve. ThisVconnection is vuseful `for certain general purposes where no lineadjustment is required. I do not Wish to be restricted tothe size, form,and proportions of the various parts, and obviously changes could be-made in the construction herein ,described Without de-v l{Orarting fromthe spirit of the invention, it eing only necessary thatl such i changesfall Withinthe scope of the appended claims 1- What is claimed is y:---Y c 1.
